摘要: 智能材料与界面材料有机结合,赋予界面材料智能特性将是研究智能材料的一个新领域. 通过水溶液以及低温水热合成方法,我们分别制备了氧化锌以及氧化钛一维无机半导体纳米棒薄膜。结合它们特殊的微观/宏观表面几何结构以及表面紫外光敏感性,在紫外光以及暗处保存的交替作用下,我们实现了表面超疏水以及超亲水的可逆转变性能。在这里,我们还讨论了一维纳米材料表面浸润性可逆转变的机理。这一原理可以拓展到其它具有类似纳米结构和外场相应性的纳米表面中。这些具有智能相应性的材料具有极其重要和广泛的工业用前景。

Abstract: Via the solution approach and the low temperature hydrothermal method, large scale aligned one dimensional (1D) ZnO and TiO2 nanorod films were prepared, respectively. Combining their special surface micro-/macro-surface structures and their special surface ultraviolet sensitivity, reversible super-hydrophobic and super-hydrophilic properties were realized via UV light irradiation and dark storage alternating treatment. The mechanism for the reversible surface wettability was also discussed. This strategy can be extended to other stimuli-responsive surfaces with similar nanostructure, which is certainly significant for future industrial applications.
